[jira] [Commented] (HBASE-5136) Redundant MonitoredTask instances in case of distributed log splitting retry

["Zhihong Yu (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-5136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13181618#comment-13181618 ] 

Zhihong Yu commented on HBASE-5136:
-----------------------------------

Can SplitLogManager maintain mapping from hash of logDirs to MonitoredTask ?
If hash of logDirs isn't found in this mapping, we create MonitoredTask.

@Prakash:
What do you think ?

>     MonitoredTask status = TaskMonitor.get().createStatus(

> User may get confused by multiple distributed log splitting entries for the same region server on master UI
